The processes of petroleum exploration, extraction, refinement, transportation, and marketing are all part of the petrochemical industry. Some additives are used in the petrol refining process. Once the entire refining process is completed, we need filtration technology to recover or recycle these additives.

Why is filtration so important in this segment? On the one hand, this may be because the exhaust gases from the production process may contain a large number of substances that are harmful to humans and the environment. To meet emission standards and to guard our health, filtration systems must be used.

On the other hand, the additives used can be costly and, if not recycled, can add significantly to the operating costs of a business. Using the right filtration system not only recovers these additives but also reduces production costs and increases efficiency.

Filtration is essentially a way of protecting the environment, and it is no exception in the case of petrochemical gas filtration. In the practice of low-carbon environmental protection today, we adhere to the guidelines of resource recycling and sustainable development to help the petrochemical industry solve the filtration problems in the production process.

To know more precisely about filtration in the petrochemical industry, you can read about filtration of applications such as Amine and Catalyst Protection. Brother Filtration, as e filtration expert, constantly offers support and solution for the petrochemical industry.

Why filtration can help to recover the expensive catalyst in the petrochemical process?

Before we explain the importance of filtration, it is essential to know what is catalyst in the petrochemical industry, and what its effect of it.

What is a catalyst?

In common parlance, a catalyst can be defined as anything that speeds up a process. A catalyst, however, is a substance that starts, speeds up, or selectively directs a chemical process without being consumed by the reaction in the science of chemistry.

Many different types of end products, including packaging for consumer goods and cleaner burning, low-emission fuels, depend on catalysts, which come in a variety of sizes and shapes. 90% of chemicals generated commercially are thought to be synthesized using catalysts.

Catalysts are employed in the refining process to transform heavy oil into useful, distillable products. To help refineries all over the world work better, they can be recycled and used with a variety of feedstocks.

What is catalyst hydrotreating?

For the purpose of eliminating over 99% of impurities from liquid petroleum fractions, such as nitrogen, sulphur, oxygen, and metals, catalytic hydrotreating is a crucial step in the petroleum refining process.

A fixed-bed reactor filled with a series of hydroprocessing catalyst layers, each of which offers a varying amount of pollutants removal to produce cleaner-burning fuels, is the typical refinery where the hydrotreating process is carried out.

What is catalyst regeneration?

Impurities in the feedstock eventually foul the catalyst during hydrotreating, which results in a loss of activity. When compared to purchasing new catalysts and discarding the used catalyst after each cycle, regenerating catalysts for reuse can restore activity, which translates to significant financial and environmental savings. Additionally, reactivation and regeneration lessen the environmental impact of using catalysts in hydroprocessing.

The downstream user’s production unit is shut down, and the spent catalyst is removed from the reactor to guarantee safe operations during regeneration. After the reactor has been unloaded, it is cleaned and examined before being reloaded with either a brand-new batch of catalyst or a catalyst that has been regenerated. The unit is put back into production after the loaded catalyst is turned on.

The filtration solution for petrochemical catalyst

To remove scale, rust, and other solid pollutants are removed from the feed by the hydrotreater, the backwash filter is a perfect choice. It can reduce heat exchanger fouling, which lengthens the period between maintenance and shutdowns, minimizes unplanned reactor downtime, and requires fewer catalyst replacements.

Removal of water from hydrotreater feedstock, water from stabilized gasoline, and liquids and solids from recycled hydrogen. The coalescer and separator filter cartridge can be adopted, which avoids unplanned reactor shutdowns, and heat exchanger fouling, and prolongs the lifespan of the catalyst bed.

Additionally, it can protect downstream machinery, upholds liquid fuel specifications, and lowers maintenance costs. And coalescer and separator filter cartridge can offer hydrogen compressor operation with high efficiency.

To remove scale and rust from the desulfurized product, as well as other solid impurities, a high flow filter cartridge can be applied. It lowers maintenance and labor expenses while safeguarding equipment downstream.
